Achieving zero emissions in the energy sector by 2050 is technically and economically possible. Indonesia can modernise its economy through various green projects.
Bill C-12 is not a plan for Canada to reduce its greenhouse gas emissions, but it would set targets to help it succeed.

If Canada began to reduce its greenhouse gas emissions by about four per cent per year, we could still meet our 2030 climate targets.

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.
Decarbonizing maritime transportation will require a major shift towards alternative fuels.
Shipping companies are expected to halve their greenhouse gas emissions by 2050.
NASA has launched all of its space shuttle missions using hydrogen as fuel.
Ever watched a space shuttle launch? The fuel used to thrust these huge structures away from Earth’s gravitational pull is hydrogen. Hydrogen could also be used as a household energy source.

The development of a hydrogen charging station has made it possible to run vehicles without producing greenhouse gases.
Are there greener pastures ahead for gas?
By embracing natural gas made from renewable sources, we can still use gas for heating, cooking and industry, while slashing greenhouse emissions and even keeping much of the same infrastructure.

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 New Zealand government is introducing legislation to become zero-carbon by 2050, but will consider new permits for coal mining, offshore oil drilling and fracking on a case-by-case basis.

Natural gas is touted as a “bridging fuel” to displace coal while moving to a low-carbon economy. In New Zealand, this is shortsighted and could lead to stranded assets and hold back renewables.
The European Investment Bank’s funding of the Trans Adriatic Pipeline will harm the climate and makes little financial sense.
The development of alternative airline fuels needs serious support from national governments if we are going to see greener skies overhead any time soon.

Regulators, rebates and retaining bus services - Plaid’s transport policy offers a lot, but little explanation on how to fund it.
This wouldn’t be a problem if propane was renewable.
Converting renewable energy into electricity is one thing; converting it into fuel is quite another. The vast majority of global energy demand is for fuel, and a renewable source could help us heat our…
