If you run a business or work in one, environmental reporting is no longer something you can quietly push to the back burner. Governments, investors, customers, and employees are all paying close attention to how companies treat the planet and the pressure to be transparent has never been greater.

Whether your company is just starting its sustainability journey or looking to strengthen an existing ESG (Environmental, Social, and Governance) framework, knowing exactly which environmental issues you are required to report on is the critical first step. Get it wrong and you risk regulatory fines, reputational damage, and losing the trust of the people who matter most to your business.

This guide breaks down the top 10 environmental issues companies must report, explains why each one matters, and points you toward the tools and resources that will make the process a whole lot easier. Catch up on previous posts on environment and sustainability.

10 Environmental Issues Companies Must in ESG Report.

1. Greenhouse Gas Emissions (GHG)

Greenhouse gas emissions are at the very top of every environmental reporting framework in existence, and for good reason. Carbon dioxide, methane, and nitrous oxide are the primary drivers of climate change, and companies are now expected to measure and disclose how much of these gases their operations produce.

Reporting typically follows the GHG Protocol, which divides emissions into three scopes. Scope 1 covers direct emissions from sources your company owns or controls, such as company vehicles and on-site combustion. Scope 2 covers indirect emissions from purchased electricity or heat. Scope 3 is the broadest and most challenging, covering all other indirect emissions across your entire value chain, including suppliers, business travel, and product end-of-life.

Most major reporting frameworks, including the Global Reporting Initiative (GRI), the Task Force on Climate-related Financial Disclosures (TCFD), and the new ISSB standards, require GHG disclosure. Even if it is not yet mandatory in your jurisdiction, investors increasingly demand it.

2. Energy Consumption and Energy Efficiency

Closely linked to GHG emissions, energy use is a standalone reporting requirement across virtually every major framework. Companies must disclose how much energy they consume, what sources that energy comes from, and what steps they are taking to improve efficiency or transition to renewables.

This includes electricity, heating, cooling, and fuel consumed across all operations. Many frameworks also ask companies to report on the percentage of their energy that comes from renewable sources, which has become a key metric for ESG investors and rating agencies.

Reducing energy consumption is also one of the fastest ways to cut operating costs, so this is one environmental issue where the business case and the sustainability case genuinely align.

Recommendation: Energy monitoring devices such as the Emporia Vue Smart Home Energy Monitor allow businesses to track real-time energy usage across facilities. For smaller offices, the Kasa Smart Plug with Energy Monitoring is a highly rated, affordable starting point for measuring consumption at the device level.

3. Water Usage and Water Management

Water is increasingly being recognized as one of the world’s most critical and most threatened resources. Companies that consume significant volumes of water, whether in manufacturing, agriculture, food production, or facilities management, are expected to disclose how much water they use, where it comes from, and how efficiently they manage it.

Reporting on water goes beyond just consumption figures. Leading frameworks ask companies to address water stress in the regions where they operate, detail any water recycling or reduction initiatives, and disclose the quality of wastewater they discharge back into the environment.

The CDP Water Security questionnaire is one of the most widely recognized tools for corporate water disclosure, and many institutional investors now specifically look for CDP Water scores when evaluating companies.

4. Waste Generation and Waste Management

How a company generates, manages, and disposes of waste is a core component of environmental reporting. This covers everything from general office and operational waste to manufacturing byproducts, electronic waste (e-waste), and hazardous materials.

Companies must typically report total waste generated, broken down by type and disposal method: whether that is landfill, recycling, incineration, or composting. The move toward circular economy principles means many frameworks now also ask about waste reduction targets and take-back or recycling programmes for products at end-of-life.

5. Air Quality and Pollutant Emissions

Beyond greenhouse gases, companies must also report on the release of other air pollutants that directly affect local air quality and human health. These include nitrogen oxides (NOx), sulfur oxides (SOx), volatile organic compounds (VOCs), particulate matter (PM2.5 and PM10), and other regulated substances.

This type of reporting is particularly relevant for manufacturing, energy, transportation, and agricultural companies, though it applies to any business whose operations release substances into the atmosphere. Air quality reporting is governed by a combination of national environmental regulations and broader sustainability frameworks, and non-compliance can result in significant financial penalties.

Increasingly, companies are also expected to address how their supply chain activities contribute to air pollution, not just their direct operations.

6. Biodiversity and Land Use

Biodiversity has rapidly moved up the corporate reporting agenda, particularly following the publication of the Taskforce on Nature-related Financial Disclosures (TNFD) framework in 2023. Companies are now expected to assess and disclose how their operations affect ecosystems, wildlife habitats, and biodiversity.

This is especially relevant for sectors like agriculture, forestry, mining, construction, and food and beverage, but it applies more broadly than most businesses realize. Land use changes, deforestation, soil degradation, and the disruption of local ecosystems are all areas that fall under this reporting category.

The TNFD framework, alongside the GRI’s biodiversity standards, provides detailed guidance on how companies should identify, measure, and disclose nature-related risks and impacts. This is an area that is evolving rapidly, and companies that get ahead of it now will be far better positioned as mandatory disclosure requirements tighten.

7. Climate-Related Financial Risks

Environmental reporting has moved well beyond simple pollution metrics. One of the most significant developments in recent years is the expectation that companies disclose the financial risks that climate change poses to their business model. This is the core focus of the TCFD framework, which has now been adopted or referenced by regulators in over 40 countries.

Climate-related financial risks fall into two categories. Physical risks include the direct impact of climate events on operations, such as flooding, drought, extreme heat, or supply chain disruption. Transition risks relate to the financial implications of the shift to a low-carbon economy, including policy changes, technology shifts, and changing consumer preferences.

Companies must disclose how they have identified and assessed these risks, how they are integrated into financial planning, and what governance structures exist to manage them. This kind of disclosure is no longer just a sustainability issue, it is a core financial disclosure expected by regulators and investors alike.

8. Supply Chain Environmental Impact

Companies do not operate in isolation, and neither do their environmental footprints. Supply chain sustainability has become one of the most scrutinized areas of corporate environmental reporting, largely because Scope 3 emissions, which include those from suppliers and logistics partners, can account for more than 70% of a company’s total carbon footprint.

Reporting on supply chain environmental impact typically includes disclosure of supplier environmental audits, engagement programmes, deforestation commitments, supplier emissions data, and policies on sourcing from high-risk regions or industries.

Regulations such as the EU Corporate Sustainability Due Diligence Directive (CSDDD) and supply chain laws in Germany and France are making it a legal requirement for large companies to assess and address environmental risks throughout their supply chains, not just their own operations.

9. Environmental Compliance and Legal Actions

Transparency about a company’s environmental compliance record is another key reporting requirement. This includes disclosing any violations of environmental regulations, fines or penalties received, legal proceedings related to environmental damage, and the outcomes of those proceedings.

While this might seem uncomfortable to disclose, investors and stakeholders actually value companies that are upfront about compliance issues and can demonstrate how they have addressed them. Attempting to conceal environmental violations is far more damaging to a company’s reputation and valuation than transparent, proactive disclosure.

Many frameworks, including GRI Standards (specifically GRI 307), require companies to report the number of significant fines and non-monetary sanctions for non-compliance with environmental laws and regulations during the reporting period.

10. Environmental Targets, Goals, and Progress

The final and arguably most forward-looking requirement is for companies to disclose their environmental targets and report transparently on progress toward them. Setting a net-zero commitment is not enough on its own, stakeholders want to see interim targets, year-on-year progress data, and honest reporting on areas where the company has fallen short.

This includes science-based targets (SBTs), which are emissions reduction goals validated by the Science Based Targets initiative (SBTi) as being consistent with limiting global warming to 1.5 degrees Celsius. Companies with validated SBTs are increasingly favored by institutional investors, procurement teams, and customers.

Reporting on targets also means being transparent when you miss them. The companies that build the most credibility through environmental reporting are the ones willing to explain what went wrong, what they learned, and how they are adjusting their approach.

Recommendation: “Net Positive: How Courageous Companies Thrive by Giving More Than They Take” by Paul Polman and Andrew Winston is a highly practical guide available on Amazon. It is an excellent read for leadership teams working to define and communicate ambitious, credible environmental goals.

Why Getting Environmental Reporting Right Is a Competitive Advantage

It is tempting to view environmental reporting purely as a compliance burden, but the companies that approach it as a strategic opportunity are the ones pulling ahead. Strong, transparent environmental disclosure builds investor confidence, attracts top talent, opens doors to green financing, and creates a genuine point of differentiation in markets where customers increasingly vote with their wallets.

The regulatory direction of travel is also unmistakable. Frameworks that were voluntary five years ago are becoming mandatory. The EU’s Corporate Sustainability Reporting Directive (CSRD), the SEC’s climate disclosure rules in the United States, and similar legislation being introduced across Asia and Africa mean that the question is no longer whether your company will report on these issues, it is whether you will be ready when you have to.

Start with the issues most material to your specific industry, build your data collection processes, and work outward from there. You do not need to report on everything perfectly from day one. What matters is that you start, you are honest, and you keep improving.

Finally…..

Environmental reporting can feel overwhelming, particularly for smaller businesses or companies just beginning their sustainability journey. But at its core, it is simply about understanding your impact on the planet, being honest about where you stand, and committing to continuous improvement.

The 10 issues covered in this guide, from greenhouse gas emissions and energy use to biodiversity, supply chain impact, and climate-related financial risk, represent the areas regulators, investors, and the public care most about. Addressing them thoughtfully and transparently is not just the right thing to do. It is increasingly the smart business thing to do as well.
