Potsdam Institute for Climate Impact Research (PIK) is a leading interdisciplinary German research institute advancing the science of climate impacts and global sustainability. With around 480 international staff, PIK conducts Earth-system modelling, integrated analysis and policy advisory to support evidence-based climate solutions. Member of the Leibniz Association.

This report examines how entrenched political and market structures hinder agribusinesses from transitioning to sustainable models. It identifies three systemic “lock-ins” and outlines how policy reforms, financial incentives, and political commitment can unlock agribusiness potential to drive food system transformation at scale and pace.

This guide interprets the Greenhouse Gas Protocol Corporate Standard for U.S. public sector organisations. It provides standardised methods for accounting and reporting greenhouse gas emissions, supports inventory quality, and addresses public sector-specific scenarios such as leased assets, joint operations, and regulatory compliance.

ICLEI – Local Governments for Sustainability (ICLEI) is a global network of 2,500+ cities, towns and regions across 125+ countries. It supports local governments with technical assistance, peer exchange and tools to accelerate climate action, sustainable urban development, biodiversity protection and resilient, equitable and circular outcomes.

This supplemental report provides standardised methods for communities to estimate greenhouse gas emissions and carbon removals from forests and trees. It expands the global protocol for community-scale greenhouse gas inventories by offering detailed guidance for accounting Scope 1 emissions and removals, supporting local climate action planning and integration with national inventories.

The greenhouse gas protocol’s land sector and removals initiative aims to develop internationally accepted corporate guidance for accounting and reporting emissions and removals from land use, bioenergy, and carbon removal. It seeks to improve transparency, support target-setting, and align with climate goals through a multi-stakeholder, science-based process.

The GHG protocol agricultural guidance provides a framework for agricultural companies to develop greenhouse gas (GHG) inventories aligned with the Corporate Standard. It offers sector-specific methodologies to account for direct and indirect emissions, carbon stock changes, and unique agricultural factors such as land use change and biological processes. The guidance enhances consistency, transparency, and usability of agricultural GHG data for decision-making and reporting.

The report explores how board directors perceive and advance climate action. While most recognise its importance and opportunity, competing priorities and knowledge gaps hinder progress. Local Chapters of the Climate Governance Initiative are shown to support action through resources, training, and peer networks across varied global contexts.

The GHG Protocol Product Life Cycle Accounting and Reporting Standard provides a globally consistent framework for companies to quantify and publicly report greenhouse gas emissions and removals associated with individual products across their life cycle. It enables informed emissions reduction strategies and supports performance tracking, supplier engagement, and product differentiation.

The Policy and Action Standard provides a consistent framework for estimating and reporting the greenhouse gas (GHG) impacts of policies and actions. It outlines methods for ex-ante and ex-post assessments, defines principles of GHG accounting, and offers guidance on defining policy boundaries, estimating baseline emissions, and assessing uncertainty to support transparent, accurate decision-making.

This report outlines a standardised framework for governments to design, assess, and report on greenhouse gas mitigation goals. It defines principles, methodologies, and accounting requirements to support consistent and transparent emissions tracking and goal evaluation at national and subnational levels.

This report assesses cost-effective methods to reduce methane emissions from enteric fermentation, manure management, and rice cultivation. It outlines region-specific strategies and underscores the need for research, regulatory frameworks, and cross-sector collaboration to support implementation and scale-up of mitigation solutions.

Nuclear energy is gaining momentum as a reliable, low-emissions electricity source. The report outlines growth drivers, investment needs, emerging technologies such as small modular reactors, and policy frameworks required for scale-up. Financing challenges, supply chain risks, and workforce planning are key to realising nuclear’s role in future energy systems.

The report outlines strategies and case studies from global cities integrating nature into urban development to address climate and biodiversity challenges. It highlights the importance of public-private collaboration, compact planning, and nature-based infrastructure in fostering resilient, sustainable, and equitable cities. Solutions are scalable and grounded in real-world examples.

Kantar is a global leader in marketing data, insights and analytics, supporting over 96 of the world’s top 100 advertisers across 90+ markets. It combines behavioural and attitudinal data to inform brand strategy, creative testing, media effectiveness, customer experience and sustainable growth.

This report identifies significant planning, finance, and data gaps in climate investment needed to transition global agrifood systems. Annual climate finance must increase by at least 40 times to USD 1.1 trillion by 2030. Current national commitments underestimate actual requirements, highlighting the need for clearer targets and improved data collection.
