The exploitation of fossil fuels emits CO₂, the main cause of global warming.
The Earth’s past shows the key role of CO₂ on climate for 4.45 billion years, and how human industrial activity has disrupted its cycle at an unprecedented rate over the past 160 years.
The Rhenish Brown Coal Field in Germany. Germany is one of 18 developed countries whose carbon emissions declined between 2005-2015.
Reducing emissions doesn't have to conflict with a growing economy, as these 18 developed nations show.
While countries recognise the urgent need to reduce their greenhouse gas emissions by favouring greener energies, the ever-increasing demand for electricity has led to rising coal consumption.
Corn cobs dried up after a drought in eastern France in 2015.
The climate issue cannot be considered less urgent than the social or economic crisis.
Whether to attending a conferences or giving in to a meeting, the global research community is keen on air travel. That’s a habit that needs to change.

Buildings are responsible for 40 per cent of energy-related carbon dioxide emissions worldwide. Efforts to reduce emissions should no longer be voluntary.
Steel mills, like this one in Hamilton, Ont. emit greenhouse gases. Ontario must reduce its emissions from 161 megatonnes to 143 megatonnes by 2030.
Ontario's new environment plan scores poorly on conservative ethos.

The country's carbon emissions should level off again soon.
Economists have searched for the mythical balance between the cost of climate action, and the future cost of doing nothing.
For decades, economists have pondered the 'social cost of carbon' - the price worth paying to avoid the future costs of greenhouse emissions. But a new analysis suggests this quest is impossibly complex.
Working together, people and technology companies can make a lot of progress.
Amazon, Facebook and Google have lofty goals for their effects on global society. But people around the world are still waiting for the positive results. Here's what the tech giants could do.
The Internet of Things could improve quality of life, but it will also consume vast amounts of electricity and boost greenhouse gas emissions.
The Internet of Things is contributing to climate change. Innovation in computer design could help mitigate the problem.
Lithium batteries offer renewable energy electricity power storage.
High quality Li-ion batteries could help Africa optimise renewable energy.
The basic principle of ecodesign is the concept of life cycle, which aims to take into account end-of-life considerations.
To reduce the impact of its activity on the environment, a company must take into account not only the effects generated by its production, but also the end of life of its products.
California and the Trump administration are going different directions on mileage standards.

Law scholars from California unpack the legal questions raised by the Trump administration's plan to roll back mileage standards and revoke California's ability to set more stringent rules.
The Gillard government’s carbon price had no effect on the aviation industry.
If Australia is to meet its climate targets, radical measures could be required to reduce emissions in sectors such as aviation.
Livestock is a significant source of methane, a potent but short-lived greenhouse gas.
New research has suggested a fresh way to account for greenhouse gases with different lifetimes in the atmosphere.

Canada wants to move towards a green economy and meet its Paris Agreement targets, but it has also just taken ownership of a pipeline. How can the federal government deal with this paradox?
The shipping industry has been slow to use greener fuels.
Shipping is becoming greener, but this brings new safety challenges.
There’s more to e-waste than the discarded monitors, cell phones and other electronics.
No amount of post-consumer recycling can recoup the waste generated before consumers purchase their devices.
Other countries have carbon budgets. Why not Canada?
Canada has made strides, but we're still far from being a climate leader. Budgeting our emissions would help bring us to the front of the pack.
