Offsetting greenhouse gas emissions can be an effective tool for limiting global warming. But many offset projects fail to meet their GHG reduction targets.

Producing energy from harvested trees and other plants – bioenergy – might sound like a greener option, but it’s not a simple issue.
The most comprehensive Australian carbon budget assessment completed to date shows the nation flip-flops from source to sink of carbon emissions, depending on the prevailing conditions.
A group of agricultural and soil scientists has serious concerns about the way credits are awarded for soil carbon sequestration in Australia.
While the ACCC, ASIC and a new senate inquiry begin to flush out greenwashing, we take a closer look at dodgy climate claims. Complaints and court cases are stacking up. Here’s what you need to know.
Market volatility and rising development costs have led to an increase in the risk premium in recent years.
The world is facing one of the century’s biggest challenges: How to nutritiously feed the growing population, address climate change and not destroy the ecosystems on which we all depend for life.
The US has required motor fuels to contain 10% biofuels since 2005. As this program nears a key milestone in 2022, farm advocates want to expand it while critics want to pare it back or repeal it.
The goal of carbon neutrality changes everything. Canada can no longer limit itself to solutions that partially reduce emissions here and there. The chosen solution must be zero emissions.
Bill C-12 is a step in the right direction, but its not enough to meet Canada’s goal for a decarbonized economy.
Attempts to formalise charcoal production have been largely unsuccessful.
David Littleproud on The Nationals and net zero
Michelle Grattan discusses the National party's feelings towards a 2050 carbon neutral goal with deputy leader David Littleproud.
Zero emission? Carbon neutral? Carbon negative? What does it mean to achieve ‘net-zero’ emissions?
Universities are vital hubs of research and teaching on climate change and, as big organisations, produce significant emissions themselves. They should therefore lead action to limit climate change.
Energy efficiency and electrification should lead the effort to decarbonise society, not hydrogen.
Energy companies are marketing a new fuel: ‘renewable’ natural gas. But it’s not the same from a climate change perspective as wind or solar energy.
Social tipping interventions have the potential to pave the way for rapid change and avert climate change.
The Drax biomass plant in Yorkshire is the first in the world to pioneer carbon capture and some specialists see it as it has a bright future. But hold the rosy headlines.
Deriving fuel from trees costs more than wind and solar power and it emits more carbon than coal. There are many heated debates about this kind of energy, known as forest or woody biomass.
The pioneering legislation is ten years old – and the latest science means it now does not go far enough.
