A more robust approach to global warming is needed if we are to avoid catastrophe. Unlike the recent financial crisis, there is no bailout option for the earth's climate.
It doesn't really matter who owns things so long there is enough competition, which means lower pricing, better quality goods, more variety, and an economy where the consumers are the big winners.
If the world is to avoid a collision with nature - one that humanity surely cannot win - we must act boldly on every front, particularly with respect to carbon pricing and the coherence of our economic and energy policies.
There probably could be some mileage in running a comparative study about how best to finance electoral campaigns around the world.
I feel confident that leaders will rise to this challenge with a stronger commitment to tackle climate change and seize the economic opportunities that a post-carbon world has to offer.
Governments must address inconsistencies in their energy strategies, consider the links with broader economic policies, and stop sending mixed signals to consumers, producers, and investors. In particular, they must assess whether the right regulatory arrangements are in place to allow clean-energy investments to compete on a risk-return basis.
Some challenges remain, but the bottom line is that low-carbon options can and should play a much greater role in energy supply.
When, as an individual, you are not paying taxes, it is evasion. As a corporate, it is legal shrewdness or tax engineering.
Ensuring a better future for all South Africans will require increased access to higher education, a stronger and fairer labour market, deeper participation in regional markets, and a regulatory framework that fosters entrepreneurship and allows small businesses to thrive.
If we can rid the world of financial centres that thrive on lack of transparency, non-cooperation, and weak regulation, an important step towards a fairer and cleaner world economy will have been achieved.
It is not good to cut exports or imports.
Most businesses do not take governments seriously when it comes to climate, primarily because many governments have inconsistent and incoherent policies and then often keep changing them, sometimes retroactively. This makes businesses reluctant to invest in greener technologies.
The whole banking sector in Mexico was literally bankrupt. For whatever reason, instead of intervening in the sector or supporting the banks, the government expropriated them. We went through the very laborious period of selling the failing banks to the wealthy people of Mexico.
European leaders cannot afford to be afraid. The refugee crisis is not one from which they can opt out. No magic wand will empower leaders to transport more than a million people back across the Aegean and the Bosphorus to Mosul and Aleppo, or across the Mediterranean to Eritrea, Somalia, and Sudan.
The home is the planet. Unless you're a Martian, you know, we're sharing the planet. And - and the emissions don't stop and CO2 doesn't stop with the border between France, Spain or between Canada and the United States.
Some politicians fear the burden that migrants will impose on local communities and taxpayers. Others fear extremists masquerading as genuine refugees.
In a globally interdependent world, a better financial and investment system cannot be achieved on a country-by-country basis. There may be no one-size-fits-all model for economic development, but without global standards and complementary regulations, the long-term outlook for the world economy will remain bleak.
Every single stage of reform becomes more difficult because you use political capital.
Every country faces its own obstacles to reaching gender equality, and to make a real difference, we must change public policies in tandem with stereotypes, attitudes, and behaviors.
Providing investors with recourse against governments is valuable.
